Creating new request & response objects could be easier

[jakearchibald]

In specs, if I want to create a new request, I'm creating the request object, then creating the headers object, then hooking the two up.

With responses it's slightly more complicated, as I need to deal with the trailer promise too.

Is this worth simplifying?

[jakearchibald]

Otherwise, I need to export https://fetch.spec.whatwg.org/#concept-response-trailer-promise.

I guess you're talking about the platform objects, not the concepts? It's probably good to introduce an abstraction for them, yes.

[jakearchibald]

Yeah, I mean the platform objects. I'm doing this for background fetch https://wicg.github.io/background-fetch/#create-settled-fetches-algorithm. I'm attempting a more specific description of how requests/responses come out of the cache.

I guess service workers and the cache API need this too in some way. Should probably take that into account too.
